So. There's a research scientist, usually out in the field somewhere and usually by himself or in a small tight-knit team. He's really into whatever most frequently obscure and seemingly useless research he's doing, when all of a sudden some big burly military guys come out of nowhere, put a stop to aforementioned research and carry him off against his will for their own purposes. Where he will usually find something even more fantastic than what he was doing, and somehow mildly relevant.
Whenever one of these characters is pulled in, they typically describe vague and often ludicrous hypotheses as theories and are actually offended when proof is demanded of them. Narratively, this is also used as quick character development for the scientist (and sometimes for the people who take him). Usually they are the Only Sane Man who proves time and time again that their suggestions are invaluable to success of their project.
The trope is named after Niko Tatopoulos from the 1998 Godzilla film, who is referred to by the military personnel as "the worm guy", as they took him from Chernobyl where he was studying earthworms. And they couldn't pronounce his actual name.
Compare to Ignored Expert, Kidnapped Scientist and The One Guy with a Brain. Contrast with Agent Mulder, who is recognised as an unscientific crank, but is right anyway. See also Haunted House Historian.
- Ultimate Marvel's version of the Falcon is introduced in a version of this trope: he's in the Amazon when the military guys come for him by helicopter, and then he unveils his wings and flies up to meet them. He's treated a bit more respectfully than usual, though he does have to stand his ground to get the Black Widow's first name. The relevance of his research to the mission is that he was searching for ways to communicate with the afterlife, and hypothesizes the situation might have to do with broadcasts from beyond death, which turns out to be true, albeit in a slightly less literal manner.
- The whole point of Global Frequency was to link up a wide range of Worm Guys so that there was always someone on hand who knew what to do when rogue cyborgs went berserk, or a Soviet sleeper agent risked opening a wormhole in San Francisco, or London has to be saved by Le Parkour, or whatever left-over Cold War super-science threatens the world this time.
- The present-day heroine of The Wake is Whale Lady Lee Archer, pulled away from studying cetacean communication at sea in order to study a captured undersea alien. The folklorist and hunter she teams up with also indicate they were recruited in a similar way.
- The trope's namesake, Niko Tatopoulos from the 1998 Godzilla. He was researching the growth rate of earthworms in Chernobyl, by himself, out in the field, and suggests Godzilla was created from nuclear fallout based on a small tissue sample and radiation readings. He also gets cross when ignored about his Godzilla eggs nest site theory, which then turns out to be correct.
- Daniel Jackson in the Stargate movie—taken away from a lecture (where the lectured walked out on him) so that he can decipher the stargate. He's not interrupted while doing his research -in fact he'd more or less just torpedoed his own career- but it's along the same vein.
- Alan Grant in Jurassic Park - taken from his paeleontological dig for a preview of living dinosaurs, as The Powers That Be wanted a paelontologist to endorse them.
- However, he wasn't making hypotheses based on little to no evidence. That was Malcolm's job.
- Final Fantasy: The Spirits Within: Dr. Ross is the Plant Lady.
- Volcano - the two (female) earthquake scientists are called out to the field to create an explanation why a Los Angeles Department of Water and Power employee was cooked to death in a manhole in McArthur Park.
- The Day After Tomorrow with Dennis Quaid's character.
- Michael Caine as Dr. Brad Crane in The Swarm. He's the world's foremost expert on killer bees, and lives out of his van as he drives across America. Despite this, every (sympathetic) character in the film has heard of him and respects his expertise, and when the President assigns him to dealing with the titular swarm and grants him unlimited power (!) in the process, his reaction to all of this is essentially a calm, "I knew this day would come".
- The Core with Aaron Eckhart's character, and with the guy who invented Unobtainium (no, really, that's what it was called!).
- Nicolas Cage in The Rock, is a special case. He is an FBI agent trained to disarm chemical weapons so he is hardly a civilian. However, he was never trained to do so while fighting a highly experienced team of rogue Marine Recon soldiers. He also never had to deal with a weapon that could kill tens of thousands of people.
- The drillers in Armageddon are a blue collar version of this.
- Same as the drillers in The Abyss.
- Indiana Jones in Raiders of the Lost Ark, although he's called out of class at the university, rather than the field.
- Vito Cornelius in The Fifth Element: The Priest Vito Cornelius is one of the only people with knowledge of the advanced aliens and their enemies, passed down to him from the priest who made first contact with them.
- The team in Alien vs. Predator are recruited this way, although not all of them are scientists— heroine Alexa Woods is a mountain guide and survival expert.
- Michael Crichton likes this trope:
- In The Andromeda Strain, the doctors in the Wildfire team were rounded up by the military and taken to the facility. One of them was even pulled out of surgery. Granted, they had agreed to this beforehand. They'd just agreed to it years earlier and had no idea that they were about to be "activated" until the soldiers showed up. In at least one case, the guy who signed up had believed it was all just paranoia and there was no chance he'd ever have to follow through.
- The original Jurassic Park novel is pretty much the same in this respect as the film. The book makes it clear, however, that Alan Grant is an experienced doctor of palaeontology and respected in his field, including an apparently well-received book for kids about Dinosaurs. He's pulled into it because his main financial backer wants an endorsement to his creations' authenticity: Grant is never 'the worm guy'; more 'the famous expert we need to tell people this is the real McCoy'. Malcolm (who is a mathematician and was involved as a consultant on the risk-factor calculations) comes much closer to the trope considering how Hammond dislikes him and his initial predictions of doom and gloom about how unstable the entire system is, until events prove him completely right.
- Norman Johnson in Sphere, a psychologist carried off by the millitary to study aliens. As with the Andromeda Strain example above, Norman had agreed years ago to help with a First Contact situation if one ever arose (and was even the one who created the First Contact plan), but had privately considered the idea ridiculous (and agreed to create the plan because he was in dire need for the funding money), and was astonished to be called up because it had actually happened. Once on the field, the rest of the group is skeptical about what a psychologist can bring to the situation, but Norman is the only one who sees the warning signs when the Closed Circle that they are stuck in makes the Fatal Flaw of the rest come roaring out and he is the only one with the psychological stability to manage the Reality Warper powers of the Sphere.
- The historians of Timeline, though in this case they were ripped from their research by the corporation that was funding it, to work on something related on why they were funding it.
- On Congo, Dr. Elliot and Ross are the two "worm people" of the expedition, and come very handy as it goes by: Elliot's expertise in animal (gorilla) psychology provides the team with insights to fight the Killer Gorilla group on the City of Zinj and Ross, a self-proclaimed "console hot-dogger", is capable of handling the expedition's computers and analyze their data much better and faster than the normal procedure of sending the data to HQ in Texas-which is necessary when the jamming of a rival expedition and later solar disturbances completely cut them off.
- In Animorphs, Marco's dad is working on a research project that leads him to discover Zero Space. A Wham Episode results: the Yeerks attempt to capture him to work for them, forcing Marco to reveal The Masquerade to his father and drag him into hiding to escape.
- Robert Langdon in Angels & Demons is (allegedly) an art historian example.
- Jules Verne's Facing the Flag revolves around a Worm Guy who's kidnapped when sinister forces see the warfare potential of his chemical experiments. High adventure and submarine chases ensue.
- Perfectly describes Kim Delaney's character in the miniseries 10.5.
- The aforementioned Daniel Jackson is taken further in the show: Stargate SG-1 turns him into a full-on case of You Have to Believe Me. Apparently, he's been ranting about aliens all along, and, shockingly and surprisingly, he's been met with disbelief.
- Threshold concerned an entire task force of Worm Guys, taking on an Alien Invasion via Infection.
- In the 2008 Fox series, Fringe, Walter Bishop is a Trifecta: Omnidisciplinary Mad Worm Guy. Literally mad, BTW: he's been in an asylum for 17 years as the story opens.
- A third season episode has an expert on insects referred to as "The Bug Lady" show up when an extinct species of beetle reappears eating its way out of human hosts.
- Another 2008 series, Sanctuary features forensic psychiatrist Dr. Will Zimmerman. In the pilot, he discovers evidence that a mysterious boy is linked to a murder case. When his own colleagues refuse to listen, Zimmerman ends up being hired by the titular organization.
- This happens in Lost when associates of the rich and powerful Charles Widmore are sent out to round up a team which is meant to travel to the island and capture Benjamin Linus. This team includes a physicist who spent his whole life studying time travel and a paranormal investigator.
- Dark Skies has this happening to a young Carl Sagan.
- Mission: Impossible, the series, abuses this. While gathering them isn't an issue, quite a few of the Worm Guys on their roster. Includes a trapeze artist, a safe-cracker, the "World's Strongest Man", and such. In the pilot, the World's Strongest Man is used SOLELY for his ability to lift a large suitcase, filled with, at max, two people plus equipment.
- Dr Liara T'soni in Mass Effect. She gets recruited by the crew of the Normandy whilst out in the field on an Ancient Prothean dig-site. After rescuing her from a group of Saren's mercenaries are attempting to do the same, she is brought on to be their resident Prothean expert. In a nice subversion, when Shepard confirms her theories on the Prothean extinction are indeed correct, which have earned her ridicule amongst her peers, she shows skepticism how Shepard themselves has any evidence. Shepard then reveals their experience with a Prothean beacon that downloaded a repository of their knowledge directly into their mind as well as a warning about the Reapers.
- it should be noted, however, that she wasn't recruited solely for her scientific experience, but because she's the daughter of the villain's dragon. She also admits that, despite her youth (relatively) being the main factor in ridicule and skepticism among her peers, her theories did not have the solid piece of proof, but was more through connecting patterns that she found.
- It's also amusingly possible to make her mandatory recruitment rather redundant just by delaying it as long as possible; Liara is increasingly irked that Shepard and company casually discuss incredible breakthroughs in Prothean and related fields they made in just a few days compared to her lifetime of research. Granted, she's the one to point the way to Ilos in the end.
- Milo Thatch in Atlantis: The Lost Empire. Although he was planning on resigning his position anyway, fed up with not being taken seriously by the board of directors at the museum.
